[OE-core] [PATCH 3/6] devtool: add: add an option to fetch remote source

[Paul Eggleton]

Add a -f/--fetch option to fetch a remote URI (into the already
specified source tree path) and set this as SRC_URI within the recipe.
This simply wraps around the existing functionality in recipetool.

Implements [YOCTO #7644].
